- A high pressure oil seal is essentially a mechanical barrier that seals the interface between moving and static parts, ensuring that oil or other lubricants remain within the system while preventing contaminants from entering. They are typically made from robust materials such as rubber, polyurethane, or PTFE (Teflon), each with unique properties suited to different operating environments and pressures.
- Overall, the front hub oil seal may be a small part of your vehicle, but it plays a crucial role in keeping your front hub functioning smoothly and efficiently. By keeping an eye on the condition of your front hub oil seal and performing regular maintenance, you can help prevent costly repairs and keep your vehicle running smoothly for years to come.
This type of oil seal can withstand only low speed and friction. It is recommended in places where thick fluid or grease is to be sealed. This is not recommended for difficult applications.
0.4 to 1.6 μmRa,
1.6 to 6.3 μmRz
2. For rubber O.D. wall type:
1.6 to 3.2 μmRa,
6.3 to 12.5 μmRz
(Firmly affixes the oil seal and prevents leakage through the seal O.D.)
Oil seals, also known as rotary shaft seals, are a type of gasket used to prevent lubricant leakage and contamination in rotating machinery by creating a barrier between the moving and stationary parts.
What are oil seals?


Metal-cased oil seals are usually installed in a housing bore made of the same material. This allows for equal expansion and contraction of the materials during operation, preventing leakage. This type performs best when used in a steel housing.
Generally, oil seals vary in materials and types based on the corresponding application. Common materials include:
6. AMOUNT OF LUBRICANT: Seals perform better when lubricated but some machines will go through some dry spells. When this occurs using a leather or PTFE seal will be more beneficial as those type of seals can operate with less lubrication.
